To @ZZ whom may concern.'

Be it known that I, ROBERT ADAMS, a subject of the Queen of GreatBritain, residing at N o. 7 Great Dover Street, Southwark, in the countyof Surrey, England, engineer, have invented certain new and usefulimprovements in means andapparatus for opening, adjusting, closing, andsecuring objects hung on hinges or centers, such as easements, fan- IOlights, louvers, ventilators, lanterns, and skylights an'd doors, ofwhich the following is a specilication.

My invention relates to improvements in means for operating revolvingwindow-sashes and other analogous devices; and it consists,

essentially/,in a bell-crank lever pivoted tothe window-easing andconnected at one end bya link or arm to the sash to be revolved. Theother arm of the bell-crank lever is connected 2O by means of a rod orarm to a vertically-moving the manner of operating the same.

able bar operated by a bell-crank lever, so that v designates the windowframe or easing, and 2 the window-sash, which is centrally pivoted insaid casing. n

3 designates a bell-crank lever, pivoted to the window-casing at 4. Onearm of this 4o lever carries a pivoted link or arm, 5, which is securedto the window-sash. To the other or short arm of the lever 3 is securedan arm or bar, 6, which is also secured to a collar, 7, on thevertically-movable rod 8. This rod 8 moves in bearings or guides 9 9,secured to the wall of the building or other convenient.

support, and is provided with a eollar,10,

which limits its downward movement by abutting against the upperbearing, 9.

To the upper end of the rod 8 is connected, by an arm, 13, one arm of abell-crank lever, 11, pivoted at 12, the other arnr of the lever beingconnected with the corresponding arm of a similar lever pivoted toaetuate the next adjoining sash frame. This connection is made by therod 14, and the latter may be extended and connected to any requirednumber of bell-cranks 11, whereby a series of sashframes may be openedor closed simultaneously, as in a railway-car having ventilatorscomposed ot' hinged sashes. The other arm of the bell-crank 11 isconnected by means of a link, 13, to a vertically-movable rod, 8,sliding in eyes 9% The lower end of said rod is threaded, and engageswith a sleeve, 16, having a female thread and provided with a mitergear,17, which meshes with a second drivingmiter, 18, having a squaredbearing, 19, which receives a crank, 19. Both the gears 17 and 18 havebearing within the casing 15, as shown in Fig. 3, and as the crank 19 isoperated the sleeve 16 will revolve and draw the rod 8 down, or raiseit.

In order to secure perfect fit and retain all the parts securely inplace, I prefer to employ a tube, 20", the lower end of which isthreaded and screwedinto an aperture in the easing 15.

The operation is as follows: VVhen the sash is in the position shown inFig. 1, and it is 'desired to revolve the same, and thereby close thewindow, the rod Sis operated by revolving the crank 19a in the properdirection, thereby raising said rod 8 and the short arm or lever 3,whichis connected to said rod. This movement also actuates the bell-crank 11by means of the link 13, and communicates the action to the next windowthrough rod 14, causing lever 3 to assume the position shown in Fig. 2,thereby revolving the sash and closing the Window.
